Press Release: Semantic shifts were key factor in decline of classical liberalism, argues new study

Key concepts central to the Western tradition of classical liberalism have shifted dramatically in meaning since the late 19th Century, according to a new scholarly website, Lost Language, Lost Liberalism (4L), released today (Tuesday) by Professor Daniel Klein in partnership with the Adam Smith Institute.

4L shows that the English-language discourse of Western Civilization underwent a watershed change during the period 1880-1940. 4L focuses on changes in the meaning of words, and suggests that these changes played an important role in the decline of classical liberalism in the politics of the English-speaking world.

Ten central words are treated: liberal(ism), liberty, freedom, justice, property, contract, equality, equity, law, and rights.

Up to about 1880, people understood these terms particularly for certain salient classical liberal meanings. But then, from 1880, the culture changed and meanings became upset or confused. 4L provides vast compendia of quotations in which the central words are used. The changes were a move toward collectivization, a favor for greater governmentalization of social affairs.

For each of the ten words, the website provides quotations showing how collectivists innovated, often assaulting the classical liberal meanings and flaunting innovation. The website also provides many rejoinders by authors who objected to the assaults. The site shows the debate over the meaning of each word.

The website presents tables capturing the classical liberal meanings of the words, and the changes.

The site also provides many ngram diagrams, verifying that a profound shift occurred from 1880.

The site also provides a vast collection of quotations testifying that the shift came by new generations, which talked one way, displacing older generation, which had talked another way.

4L shows that Western Civilization not only changed direction after 1880, it altered the meanings of its most important words.

Klein claims that today we are still stuck in the ruts of those changes; his message is that we need to recover the meaning and culture of the original liberalism. 4L is part of Klein’s broader ambition to advance understanding of the original arc of liberalism, its ascent, its decline, and its bearing on today.

Daniel Klein is professor of economics at George Mason University, where he leads a program on Adam Smith. He is also JIN Chair at the Mercatus Center at GMU and Associate Fellow of the Ratio Institute, Stockholm. He is the editor of Econ Journal Watch, and the author of Knowledge and Coordination: A Liberal Interpretation (Oxford University Press, 2012). The Adam Smith Institute recently interviewed Klein about another project called Liberalism Unrelinquished.

4L is authored by Klein, but the collecting of quotations was chiefly the work of Ryan Daza, an independent research and collaborator (and former student) of Klein’s.

Forthcoming ASI research on education quality is featured in City AM

A forthcoming report on the link between education quantity and economic growth – written by ASI Fellow Gabriel Heller Sahlgren – was featured in City AM.

Read the article here.

In a forthcoming report for the Adam Smith Institute (ASI), Gabriel Heller Sahlgren has shown that “the relationship between education quantity and economic growth is shaky at best”. Indeed, “there is currently no robust support for the idea that education quantity increases countries’ economic well-being (at least in developed countries).”

In contrast, Sahlgren’s own econometric research and global literature review in the ASI report shows that education quality – as measured by international test scores, for example – has a very powerful impact on economic growth. In fact, the results are stunning.

Ben Southwood comments on Mark Carney’s role in the UK’s economic recovery in City AM

The Adam Smith Institute’s Head of Policy, Ben Southwood, was quoted in City AM discussing Mark Carney’s role in the UK’s economic recovery.

Carney’s appointment was announced on 26 November 2012 by chancellor George Osborne. The Canadian had previously ruled himself out of the running, so the news was a surprise. If investors were overwhelmingly positive, we’d expect to see stocks appreciate as a result.

So what happened? Ben Southwood, head of policy at the Adam Smith Institute, says that the FTSE 350 barely rose that day, nor when he came into office last year, or even when Carney introduced forward guidance in August.

And since Carney’s arrival was announced the pound has strengthened against the dollar, while inflation has declined. Taken together these three facts imply that Bank policy “has been a relatively small factor in the nascent recovery,” says Southwood, “just as inflation spikes were out of the Bank’s hands in 2011, real GDP improvements are also likely coming from supply-side improvements now”.

Southwood highlights Japan as a comparison. There Bank of Japan governor Haruhiko Kuroda and Prime Minister Shinzo Abe “really have made the difference” through monetary policy. Stocks are way up, the yen is way down, and inflation has risen.
